实验证明了一种三端自转扭矩驱动的磁开关。该器件使用非局域自旋电流和自旋积累作为电流驱动磁开关的主要机制。它将电流感应的写操作与基于磁隧道结的读操作分开。写入电流仅通过金属结构，从而提高了器件的可靠性。该器件结构有效地利用了光刻能力，这对于稳健的工艺集成非常重要。
A three-terminal spin-torque-driven magnetic switch is experimentally demonstrated. The device uses nonlocal spin current and spin accumulation as the main mechanism for current-driven magnetic switching. It separates the current-induced write operation from that of a magnetic tunnel junction based read. The write current only passes through metallic structures, improving device reliability. The device structure makes efficient use of lithography capabilities, important for robust process integration.
